It takes me over one year to develop this brown colored full-protection ocarina case successfully. With special material inside to keep the ocarina in perfectly safe condition even when we drop the case to the ground intentionally. Size is around 23.8 cm in length, 17.3 cm in width and 7.5 cm in height. Metal air channel cleaner is included and it could fit well with Alto C, Alto G, AC regular Double, AC Forte Double, AC regular Triple and AC Forte Triple ocarinas.
